Trouble with three switches in bathroom

I've run power up to my renovated bathroom and set up three switches to:
1. light
2. fan
3. two lights over mirror

It all worked when it was first wired like this, but then the ceiling light kept burning out. I determined that the power source was 240 volt, so I changed that to 120 volt and now it is indicating power but nothing is working yet....

Please help!

Need more info, you ran power from where, the panel? How did you change the voltage? how are the splices made up?

I took the power from a line that runs directly from the panel. It is from a 'pony' panel that was originally used for 240 volt baseboard heating. I disconnected the neutral wire and put it on the bar at the top of the inside of the panel.

I had all the black wires connected to the power source but disconnected the fan and 'mirror' light so that I could isolate the ceiling light.

Now, the neutral wires are connected together and the power is pigtailed to the switch. The other black wire connection goes to the ceiling light...

Then you figured that out and now have 120V but your 3 things don't work?

It's possible you have ruined your 3 things, especially the motor to the fan.

It's also possible you have your 3 things wired wrong. It almost sound like you have your 3 things wired in series.

so now your fan, and two sets of lights don't work? do you have 120V to each of these items after you turn each of their switches on? I would test for 120V at each item individually by turning on each switch separately. Do you have 120V at those locations when you do this?

Am I the only one thinking this is death waiting to happen???
I think we need pictures of the panel to see what is going on before we try to assist you any further.
What you have done so far is deadly dangerous. Please stop until either we or an electrician can assist you.

Trouble with three switches in bathroom

(1). Turn off the power to the house before starting, and identify the branch circuit circuit breaker either in the main or sub-panels: Turn the branch circuit breaker supplying power to the bathroom light too-
(2). Now, take a close look at the filament of the burnt bulb - (if it is incandescent, that is) - If it is broken and dangling from one of the bulb's three internal power posts, then try and swirl it around until the filament catches on the adjacent post from which it hangs.
(3). Once this is achieved, gingerly screw the light bulb into the socket, making sure the filament doesn't dislodge, and swing loose again.
(4). Turn the bathroom switch to the on position. (Note, nothing will happen, because the power to the house is off at the main panel).
(5). Lock the bathroom door.
(6). Go to the main panel, and turn on the main power.
(7). Now, gently turn on the branch circuit breaker.
If you hear a loud explosion coming from the bathroom area, immediately turn off the branch circuit breaker, and put a piece of duct tape over the handle. Write - "Do Not Turn On" on the duct tape, and close the panel door.

Never enter the that bathroom again! Build a new one with a sun light in the ceiling and take bathes and showers in the day time. You don't need power in a bathroom...!
